Filed: 2003-07-16
Granted: 2013-06-04
Abstract: Described is a method for treating lesions. A composition comprising a radiation absorbing dye and a photodynamic agent is used to effect photocoagulation of a blood vessel carrying blood to a lesion in an animal in response to an application of energy, thus reducing a rate of blood flow through said blood vessel, and reducing a rate at which said composition exits said lesion, followed by photodynamic therapy of said lesion by applying energy to excite said photodynamic agent. Also disclosed is a method for identifying lesions, by injecting said composition into a blood vessel, applying energy to cause a fluorescing dye to fluoresce, and obtaining an angiographic image.

Abstract: La présente invention concerne des méthodes de traitement d'un tissu visant à inhiber la calcification post-implantatoire d'un tissu biologique. Dans une méthode de cette invention, un tissu est plongé dans une solution de glutaraldéhyde prétraité, autrement dit une solution de glutaraldéhyde traité thermiquement ou à pH ajusté, ou est mis en contact d'une quelconque autre manière avec une telle solution. Le tissu peut être partiellement fixé au moyen de glutaraldéhyde avant, après, ou pendant l'étape de mise en contact du tissu avec le glutaraldéhyde prétraité. Le contact avec le glutaraldéhyde prétraité produit des groupes amine libres sur le tissu, lesquels sont ensuite bloqués par la mise en contact du tissu réticulé avec un agent bloquant. Dans un autre mode de réalisation, un tissu est mis en contact soit avec un glutaraldéhyde non prétraité, soit avec une solution de glutaraldéhyde à pH ajusté pendant une durée suffisante pour que le tissu soit réticulé. Le tissu réticulé est ensuite traité au moyen d'un agent réducteur qui réduit les groupes aldéhyde et acide carboxylique sur le tissu fixé.
